In , it is being given that: AB = 5 cm, BC = 4 cm and CA = 4.2 cm; DE = 10 cm, EF = 8 cm and FD = 8.4 cm. If and , find AL : DM.

Since = = =

Then, _{ΔABC ~ ΔDEF (By SS similarity)}

Now, In _{ΔABL ~ ΔDEM}

_{<B = <E (ΔABC ~ΔDEF)}

_{<ALB =<DME (Each 90°)}

_{Then, ΔABL ~ ΔDEM (By SS similarity)}

_So, (Corresponding parts of similar triangle area proportion)
